OS Detection

["Ganga Bhavani" <GBhavani () everdreamcorp com>]

Hi,

 We are trying to use the Nmap for OS detection. Going through code, I 
 found that NMap queries 1659 ports for usual scanning but uses only 
 one open port and one closed port for OS detection. If  the user is using 
 NMAP for only OS detection (only -O), can the scanning process be 
 terninated as soon as one open port and one closed port is found ? 

 This  is to optimize this particular option.I would like to know if there any downside to this approach?

Any other suggestions to optimize the OS detection ?


Thanks,
Ganga
